Got another one! This brings my WoGE tally to a grand total of ... 2 🙂 The first one (#296) that I won was the impetus for starting off the shelf edge (link), so I guess I owe it all to WoGE! I generally don't even see the WoGE, but #332 was tweeted right when …

So, we took a day to drive across from the Taranaki basin to the East Coast basin, the forearc side of the Coromandel arc of the north island of New Zealand. I wont try to elaborate on the Neogene tectonics of New Zealand - there have been multiple episodes of shortening, extension, strike slip, and …

Today went to see an outcrop where I actually worked when doing my PhD - no time to do a full post, now but check out this picture of a nice bed with linear marks at in the center of the photo from where I measured the angle of climb on the ripples. See the …

Holy cow. It just keeps getting better. I can honestly say that my mind was blown today. We saw some mass transport deposits (MTDs) that are truly seismic in scale! Maybe not as big as the Storegga slide, but pretty dang big. For a nice paper on MTDs, go here. Since there is a student …

Wow, these rocks are fantastic! The last two days we have been looking at submarine lobes exposed along the Taranaki coast. Lobes are areas downstream of submarine channels where the gradient decreases (i.e. becomes quasi-flat) and turbidity currents deposit sand in an oblate shape emanating from the channel. For a great paper on lobes, see …

Today we went to a nice outcrop along the west Taranaki coast to look at Miocene turbidites. These deep-marine sandstones were deposited in a retro-arc setting during the mid to late Miocene - more on that in another post. The Taranaki basin is also a very productive basin in terms of hydrocarbons, with more than …

The Sabine river has a very interesting coastal history, mostly documented by Rufus LeBlanc. He shows a pattern of modern avulsions of the river updip from the coastline, leading to at least two deltas. Due to low sediment supply and the position of the coastline with the dominant Gulf winds, the deltas are wave dominated. …
